(``--vo=gpu-next`` only)
+``--tone-mapping-visualize``
+ Display a (PQ-PQ) graph of the active tone-mapping LUT. Intended only for
+ debugging purposes. The X axis shows PQ input values, the Y axis shows PQ
+ output values. The tone-mapping curve is shown in green/yellow. Yellow
+ means the brightness has been boosted from the source, dark blue regions
+ show where the brightness has been reduced. The extra colored regions and
+ lines indicate various monitor limits, as well a reference diagonal
+ (neutral tone-mapping) and source scene average brightness information (if
+ available). (``--vo=gpu-next`` only)
+
``--gamut-mapping-mode``
Specifies the algorithm used for reducing the gamut of images for the
target display, after any tone mapping is done.
